The accumulation of heavy metals in soil and crops is considered to be a severe
environmental problem due to its various harmful effects on animals and plants. Soil …

In recent years, toxic pollution from heavy metal (loid) s in soil has become a severe
environmental problem worldwide. The migration and transformation of heavy metal (loid) s …

Heavy metals and metalloids in soils are derived from the soil parent material (lithogenic
source) and various anthropogenic sources, most of which involve several metal (loid) s …

Since their introduction in the late 1970s, sequential extraction procedures have
experienced a rapid increase in use. They are now applied for a large number of potentially …

Remediation of contaminated lands in China urban areas is of great concern. Degradation
of construction facilities caused by acid rain is a serious environmental pollution issue in …

Metals in urban soils might be transferred to humans via ingestion, dermal contact, or
breathing, especially to children due to the “hand to mouth” activity during outdoor activities …

Bioremediation with microorganisms is a promising technique for heavy metal contaminated
soil. Rhodobacter sphaeroides was previously isolated from oil field injection water and …

It is a simple matter to conceptually classify trace metal fractions in soil in terms of their
relative 'availability'. However, the challenge has always been to translate this qualitative …

Potentially toxic metals (PTMs) are persistent contaminants in the soil environment. The
simple determination of their total or “pseudototal” content in soil might minimize the risks for …

Oral ingestion is the main exposure pathway through which humans ingest trace metals in
the soil, particularly for children. Metals in different soil particle size fractions may vary in …
